FLOOR-CLEANING DEVICE.

Specification of Letters Patent.

Patented Sept. 18, 1917.

Application filed May 22, 1917. Serial No. 170,250.

To all whom it may concern:

Be it known that I, FRANK O. Lrsrnn, a citizen of the United States,residing at Altoona, in the ounty of Blair and State ofPennsylvania,have invented certain new and useful Improvements inFloor-Cleaning Devices, of which the following is a specification.

This invention relates to floor cleaning devices and has specialreference to improvements in mops, or devices of a similar. characterthat are adapted to be operated with a cloth or brush for the purpose ofcleaning windows, floors, walls or ceilings.

The primary object of this device is to provide a combined improved mopand brush holder whereby the mop or brush is firmly held in position bya resilient element, which is designed to grip the mop or brush suchthat the operation is positive and the parts rigidly held, while at thesame time, the release of the cleaning element is easily accomplishedwhen desired.

Another object of this device is to provide an improved mop and brushholder having a resilient mop or brush holding portion that is actuatedby a spring that is designed to offer a substantial and gradualincreasing resistance, as the elements that hold the mop or brush areseparated.

A still further object of this device is to provide a mop and brushholder having a stationary jaw and a spring actuated movable jaw, thestationary jaw having means for attaching a handle for the convenienceof the operator, as well as to provide means for holding in a fixedposition the ends of the resilient element which controls the positionof the movable-jaw.

With these and many other objects in view which will be more readilyapparent as the nature of the invention is better understood, the sameconsists in the novel construction, combination and arrangement of partsas will be hereinafter more fully pointed out, illustrated and claimed.

It will be readily apparent to those skilled in the art to which thisinvention belongs, that the same is susceptible to some structuralchange or modification without departing from the spirit or scope of theinvention, but a preferred and practical embodiment of the same is shownin the accompanying drawings, in which- Figure 1 shows a sideelevational View of '14, or similar means.

the present invention together with a mop cloth attached thereto.

Fig. 2 shows a side elevational view of the present invention havingattached thereto the usual form of scrub brush. a

Fig. 3 shows a plan view of the mop and brush holder with the operatinghandle removed. 7 v Fig. l shows a front view of the cloth and brushengaging elements.

Similar reference characters designate corresponding parts throughoutthe several figures of the drawings.

In carrying out this invention, I use a sheet metal-preferablygalvanized ironto construct the stationary and handle engaging portiondesignated by the numeral l0,while the same thickness of galvanized ironis preferably used to construct the movable jaw portion, designated bythe numeral 11. a

The stationary aw portion 10 is designed to have a curved contour thatis adapted to fit the handle 12 at the point 13 where it is attached tothe handle by means of rivets The uppermost end 15 of the stationary jaw10 is turned back upon itself, as at 16 to provide hollow springreceiving ears, which construction readily forms a substantial fulcrumand fastening device for the upper jaw clamping spring 17, as shown inFigs. 1 and 2 of the drawin'gs.

The jaw clamping element 17 is preferably made such that the endsthereof are each secured to the stationary jaw 10, while adjacent theends there is provided a coil 19 which is positioned in such manner thatthe coil is wound at each time the jaw 11 is moved away from thestationary jaw 10. The transverse portion of the spring 17 is designedto cross the movable jaw near the mop engaging portion 20 which isprovided with sawtooth-like surfaces 21 that readily hold the mop cloth.

For the purpose of engaging the brush, as shown in Fig. 2, the mopengaging portion of the stationary jaw 10 is preferably formed in a halfcircle, as indicated at 22, which construction readily permits the frameof the brush to be grasped.

In order to provide means for setting the brush 23 at the proper anglewith reference to the operating handle 12, there is provided anauxiliary brush holder 24 which is adapted to grip the brush as shown at25. The holder 24: is preferably provided with a slot 26 and pin 27, thepin 27 being positioned in the movable'jaw 11. The brush clamp 24:, byvirtue of the slot 26, is movable thereby permitting in a practicalmanner the introduction of brushes of different widths.

Without further description, it is thought that the many features andadvantages of the present invention will be readily apparent.

I claim:

1. A mop orbrush holding device including a stationary jaw, a movablejaw pivoted thereto having an article engaging portion disposed atsubstantially right angles to the body of the jaw and provided with aslot, a spring for forcing the movable jaw toward the fixed jaw, and anauxiliary brush carrying jaw mounted in the slot of the movable jaw andhaving a slidable engagement with the inner face of the said movablejaw.

52. A mop or brush holding device including a stationary member having afixed gripping jaw at one end and hollow spring receiving ears at theother, a handle rigidly secured to said stationary member, a movableclamping member pivotally carried by the stationary member, a spring forplacing the movable member under tension, said spring being ofsubstantially Ushaped form and having its end portions coiled andfastened in the spring receiving ears of the stationary member While itsfree transverse portion exerts a clamping pressure on the movablemember, and means carried by the movable member for engaging a brush.

3. A mop or brush holding device including a stationary member having agripping jaw at one end and integral tubular spring holding ears at theother end, a movable clamping member having a gripping aw at one end andpivotally connected at its opposite end with the stationary memberadjacent the spring holding means thereof, a spring for said movablemember having its end portions engaged by the spring holding ears of thestationary member, and an extension jaw element carried by the movablemember. 7

l. A mop or brush holding device including a stationary member having agripping aw at one end and having its opposite ends turned downwardly toform tubular. spring receiving ears,a movable member also having agripping jaw at one end andpivoted at its other end to the saidstationary member, a substantially U-shaped spring having a coilportionadjacent each end and also having the extremities thereof engagedwithin the tubular ears of the stationary member, saidspring having itstransverse portion bearing against the outer face of the movable member,and an extensible brush engaging element carried by the movable memberand located at the inner face thereof, V r i 5. A mop orbrush holdingdevice including'a stationary member having a gripping jaw, a springtei'isioned clamping member having a gripping jaw and provided with alongitudinal slotinthe body thereof anda horizontal slot in the jawthereof, and ancX- tension brush grippingelement having its body portionpassing through the slot in said jawof the movable member and alsocarrying a pin slidably engaging the longitudinal slot in the body ofthe movable member.

In testimony whereof I affix my signature in the presence of twowitnesses.
